Trefor - Llyn Peninsula
At the foot of Yr Eifl, the tallest hills on the peninsula, lies the village of Trefor, which owes its very existence to the quarries on the hills above it. Granite from Yr Eifl quarry has been used to make Olympic Curling Stones, as well as many curb stones in the larger towns and cities of England and Wales.
Views from Yr Eifi, on a clear day, extend to Ireland, the whole of Cardigan Bay, Anglesey, Snowdonia, and the northern mountains of England. The centre peak, and tallest at 1,850, is called Garn Ganol; the most seaward, and smallest peak, is Garn For, which is home to the quarry.
